Calculate fixed deposit maturity amount and interest earned based on deposit amount, interest rate, duration, and compounding frequency.

Calculate FD maturity

Enter the deposit terms to estimate maturity amount and interest earned.

Enter the deposit amount, rate, duration, and compounding frequency, then select Calculate FD.

Fixed deposit compound-interest formula

More frequent compounding generally adds interest to the balance more often. When duration is entered in months, it is divided by 12 to obtain fractional years before the formula is applied.

A = P × (1 + r ÷ m)^(m × t)

A: Estimated maturity amount
P: Principal deposit amount
r: Annual interest rate as a decimal
m: Compounding periods per year
t: Deposit duration in years

Fixed deposit calculation example

For a ₹1,00,000 deposit at 7% annual interest for 5 years with quarterly compounding, the calculator applies 20 compounding periods. Actual bank returns may differ because of bank rules, compounding conventions, premature withdrawal, and taxes.

Sample inputs

Deposit amount: ₹1,00,000
Annual interest rate: 7%
Deposit duration: 5 years
Compounding: Quarterly

Example results

Maturity amount: ₹1,41,477.82
Principal amount: ₹1,00,000.00
Interest earned: ₹41,477.82
Deposit duration: 60 months

How to use the FD calculator

Enter the one-time principal.
Add the annual rate and deposit duration.
Choose the stated compounding frequency and review maturity value and interest.

Principal, rate, duration, and compounding

Principal is the opening deposit. Rate, duration, and how often interest is added determine the modeled maturity value.

How compounding frequency affects maturity

When the same nominal rate is used, more frequent compounding generally credits interest to the modeled balance sooner. Bank conventions and product terms can differ.

Principal versus interest earned

Principal is the amount deposited. Estimated interest is maturity value minus principal before any applicable tax, deduction, fee, or penalty.

Benefits and common use cases

Compare deposit terms using consistent assumptions.
Estimate maturity for a defined time horizon.
See principal and interest separately.

Limitations and assumptions

Premature withdrawal considerations

Early closure may change the applicable rate or introduce a penalty, depending on the product. Confirm liquidity and closure terms with the institution.

Common FD calculation mistakes

Using a compounding frequency different from the deposit terms.
Ignoring premature-withdrawal conditions.
Assuming all banks apply identical day counts and rounding.
Treating the pre-tax estimate as the final amount received.

Practical tips

Match every input to the deposit document.
Compare maturity amounts for the same principal and duration.
Review interest payout and renewal instructions.
Keep emergency liquidity needs in mind.

Frequently asked questions

What is a fixed deposit?

A fixed deposit is a bank deposit held for an agreed period at a stated interest rate, subject to the bank's terms and applicable rules.

How is FD maturity amount calculated?

The principal is compounded using the annual interest rate, deposit duration, and selected compounding frequency. The interest earned is the maturity amount minus the principal.

Which compounding frequency gives a higher maturity value?

For the same principal, stated annual rate, and duration, more frequent compounding generally produces a slightly higher maturity amount.

Is FD interest taxable in India?

FD interest may be taxable according to applicable tax rules. Tax treatment depends on individual circumstances and can change, so consult current official guidance or a qualified professional.

What happens if I withdraw an FD early?

A bank may apply a lower interest rate, penalty, or other conditions for premature withdrawal. The exact treatment depends on the deposit terms.

Does this calculator include TDS, taxes, or penalties?

No. It estimates compound interest before TDS, taxes, premature-withdrawal penalties, and bank-specific adjustments.
